TTA-500 uses audiophile-grade coupling capacitors: Wimafor input and connecting driver tubes with the output amp, and Rubycon capacitors in the power filtering.

The amplifier sounds in a very warm, lifelike way and high dynamics and the sound is very linear with almost no negative feedback.

High-quality EI broadband sound output transformer provides voltage stability and constant and immediately-available energy at any volume level. The both channels use independent rectifier and filter circuits in the supply power. The sound is natural and fresh with deep multidimensional soundstage.

The audiophile grade ALPS volume potentiometer ensures minimal noises and channels crosstalk and has excellent operational feel and limits errors between the two channels.

The preamplifier input (HT input) is dedicated for using the TTA-500 as a tube power amplifier and allows to connect it to your Home Theatre system (AV receiver or amp) to drive front left and right channels - now you can use the same pair of speakers in your high-end stereo as well as in the multichannel system without switching speaker cables nor changing the amplifier.

The removable IEC power cable gives you an option to upgrade your system with a premium audiophile power cable in any time.

The TTA-500 amplifier does not only sound great but it also looks magnificently. The front and side walls of the housing are made of thick 6 mm aluminum. The vacuum tube decorative panel is finished in a modern brushed aluminum color.
